Patterns & Practices Application Architecture Guide – v2.0 (Beta 2 Release)

After the patterns & practices Application Architecture Guide – v2.0 (Beta 1 Release) , as expected the beta 2 version is now released

Key Changes in Beta 2
Beta 2 is a significant overhaul of the entire guide. We carried the good forward. We made some key additions:

  • Added a foreword by S. Somasegar.
  • Added technology considerations throughout the guide.
  • Added technology matrixes for choosing technologies, including Presentation, Data Access, Workflow, and Integration technologies.
  • Added a new Agile Architecture Method (see chapter 4.)
  • Tuned and pruned the recommendations across the entire guide.
  • Restructured the guide for simpler parts – fundamentals, design, layers and archetypes.

4 Parts

  • Part I, “Fundamentals”
  • Part II, “Design”
  • Part III, “Layers”
  • Part IV, “Archetypes"



Key Scenarios
The guide helps you address the following scenarios:

  • Choose the right architecture for your application.
  • Choose the right technologies
  • Make more effective choices for key engineering decisions.
  • Map appropriate strategies and patterns.
  • Map relevant patterns & practices solution assets.

Key Features

  • Canonical app frame – describes at a meta-level, the tiers and layers that an architect should consider. Each tier/layer is described in terms of its focus, function, capabilities, common design patterns and technologies.
  • App Types.  Canonical application archetypes to illustrate common application types.  Each archetype is described in terms of the target scenarios, technologies, patterns and infrastructure it contains. Each archetype will be mapped to the canonical app frame. They are illustrative of common app types and not comprehensive or definitive.
  • Arch Frame – a common set of categories for hot spots for key engineering decisions.
  • Quality Attributes – a set of qualities/abilities that shape your application architecture: performance, security, scalability, manageability, deployment, communication, etc.
  • Principles, patterns and practices – Using the frames as backdrops, the guide overlays relevant principles, patterns, and practices.
  • Technologies and capabilities – a description/overview of the Microsoft custom app dev platform and the main technologies and capabilities within it.
